Bosch LBD8904 Desktop Handset Station

The Bosch LBD8904 Desktop Handset Station is a robust and reliable communication terminal designed specifically for industrial environments where operational continuity and clear communication are critical. Featuring a durable fiber-glass housing and ergonomic handset, it is engineered to withstand dust, noise, vibration, and demanding day-to-day usage across manufacturing plants, warehouses, processing facilities, and infrastructure sites.

This handset station includes a built-in electronic module that handles pre-amplification and signal processing for clear audio communication. When paired with the LBD8924 Extension Amplifier, it becomes a fully functional industrial paging and party-line communication station supporting complete public address system capabilities.

For streamlined operation, the Bosch LBD8904 is equipped with three snap-action, non-locking micro-switches on the front panel — enabling paging announcements, private conversations, and customizable functions. Options such as priority call handling and siren activation can be added via simple jumper configuration, making it highly adaptable to specific safety protocols or workflow needs.

Industrial Communication Functions

• Paging — Pressing the page button enables announcements to a specific zone or the entire facility, ensuring messages are heard instantly by all personnel.

• Party-Line Communication — After call establishment, up to six users can communicate hands-free between stations without broadcasting over loudspeakers, enabling fast situational coordination.

• Duplex Conversations — Once a response is received, seamless two-way communication is enabled through the handset for private discussions.

Control & User Interface

The front panel includes a push button to mute the loudspeaker whenever privacy is required. A screw-driver adjustable volume control allows local speaker level management. Additionally, external alert indicators and additional priority functions can be integrated to support advanced emergency and operational workflows.
